"The aim of this project is to investigate whether and how health-related claim labels in food products lead consumers to choose healthier food diet and therefore, nutritional and health labeling could be considered a valid tool to fight against obesity in Europe taken into account also consumers’ personal characteristics (socio-demographic, economic, nutritional and health status etc) and psychological and emotional factors. Therefore, different aspects will be investigated using a multidisciplinary approach: 1) The prevalence of the health-related claims labels in the food market; 2) The consumers’ understanding, use, perception and attitudes towards health-related claim labels; 3) How health-related claim labels in food products lead consumers to choose healthier food diet and, therefore, these claim labels potentially help to reduce obesity prevalence in Europe; and 4) The consumers’ preferences for health-related claim labels and the role of economics, social, psychological and emotional factors. The current work seeks to contribute to this cross-disciplinary stream by further examining food carrying on health-related claims as symbols perceived by European society, focusing on consumers´ emotions, and psychological and behavioural aspects, by using concepts of economics, behavioural economics and social psychology and by the implementation of focus groups, interview experts and field experiments"
